JUICE CONCENTRATE MIXING AND DISPENSING APPARATUS

Abstract: An improved mixing and dispensing apparatus for reconstituting and remixing reconstituted juice concentrate includes a container (9), a spout (31), a cap (17) with a skirt (21) and a mixing element (7) with a shaft (33) having a handle (49) at one end and a mixing head (35) at the other end. The mixing head (35) is adapted to displace the liquid substantially radially and non-circularly and only moderately axially relative to the shaft (33) as the shaft is reciprocally displaced axially relative to the cap (17). The container (9) has indicia (13) for indicating the quantity of liquid contained therein. The container (9) generally has a non-circularly shaped cavity which, in cooperation with the mixing head (35), prevents rotational displacement of the mixing head relative to the cavity. Alternatively, a shaft opening (37) in the cap (17) and a cross-sectional profile of the shaft cooperatively prevent relative rotation therebetween.

Description: JUICE CONCENTRATE MIXING AND DISPENSING APPARATUS Background of the Invention For those with discerning taste, it is well known that juice concentrate reconstituted by stirring with a spoon tastes substantially better than that reconstituted by using a blender or by shaking a container containing the juice. The loss in taste probably results from the blending of substantial quantities of air into the juice because of the turbulent and swirling action of the blender or shaker. To the contrary, the improved taste when using a spoon probably results from the avoidance of significant inclusion of ambient atmospheric air into the mixture because of substantially reduce turbulence. However, stirring with a spoon generally requires a circular displacement of the mixture and breaking the free surface of the mixture with a handle of the spoon, which also introduces some atmospheric air into the mixture. In addition, the latter not only produces a drippy spoon when the juice concentrate is reconstituted, but also produces another drippy spoon each time the juice is re-stirred prior to dispensing thereof. Thus, what is needed is an apparatus which provides a mixer for reconstituting the juice concentrate while substantially minimizing inclusion of ambient atmospheric air in the juice without the use of another appliance or utensil such as a spoon and which, in addition, provides a container for subsequently re-mixing the reconstituted juice concentrate as needed again without the use of another utensil. Summary of the Invention An improved apparatus is provided for mixing and dispensing reconstituted juice concentrate. The apparatus generally comprises containing means, closing means, and mixing means. The containing means generally includes a container having a cavity with a relatively uniform cross-section along a longitudinal axis thereof. The shape of the cross-section is preferably non-circular, such as square or any other desired configuration. The cavity is configured with sufficient capacity to contain the juice concentrate together with the dilutant, such as water, needed to reconstitute the concentrate to desired strength. Generally, the container is constructed of molded, translucent plastic whereby a user can compare the quantity of juice contained in the container with indicia molded in or printed on a wall of the container. The closing means generally includes a cap adapted to sealingly engage an upper end of the container. The lid generally has a skirt adapted to be slidably inserted into the cavity adjacent to the upper end of the container. Alternatively, the cap may be adapted to resiliently snap over a lip spaced near or at the upper end of the container to form the sealing engagement. The mixing means generally includes a shaft connected to a mixing head. The shaft is adapted to be slidably and reciprocally displaced axially through a shaft opening spaced generally centrally in the cap. Similarly, the mixing head is adapted to be slidably and reciprocally displaced axially in the cavity. The mixing head has cutouts which are adapted to displace the liquid contained in the container substantially radially, inwardly and outwardly and substantially non-circularly as the shaft and the mixing head are reciprocally displaced relative to the container and cap connected thereto. The thickness of the mixing head is adapted such that the liquid is only moderately displaced axially as the mixing head as displaced axially. The mixing means generally includes a handle which can be grasped by either hand of a user. If desired, the mixing means may also include an upstop adapted to limit upward displacement of the mixing head such that initial displacement thereof is confined to submersion of the mixing head within the liquid contained in the container. The upstop can be releasably affixed to a selected one of a plurality of annular grooves, corresponding to the quantity of liquid contained in the container. Alternatively, if it is desired that the cavity have a circularly shaped cross-section, then the shaft is configured with a non-circular cross-section and the shaft opening is cooperatively configured such that the shaft cannot be rotationally displaced relative to the cap.

Detailed Description of the Invention As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. A juice concentrate mixing and dispensing apparatus 1 generally comprises containing means 3, closure means 5, and a mixing element or mixing means 7. The containing means 3 includes a container 9 with a cavity 11 having a relatively uniform cross-section along an axis A-A thereof 11a. Preferably, the container 9 is constructed with a square-shaped cross-sectional profile, as shown in Figs. 1 and 2, with appropriate outer dimensions, with or without rounded corners, such that the apparatus 1 can be conveniently stored in the door-shelf of a refrigerator (not shown) . Similarly, the cross-sectional profile of the cavity 11 is preferably square-shaped, or any other non-circular configuration. Alternatively, the cross-sectional profile of the cavity 11 may be circular as hereinafter described. The cavity 11 is generally adapted to have sufficient capacity to contain juice concentrate (not shown) together with the water or other liquid needed to reconstitute the concentrate to desired strength, such as a capacity of 1 quart, 2 quarts, or the like. Generally, the container 9 is constructed of molded, translucent plastic whereby a user can compare the quantity of fluid 12 contained in the container 9 with container indicia 13 molded into or printed on a wall 15 of the container 9, as shown in Figs. 1 and 2. The closure means 5 generally includes a lid or cap 17 adapted to sealingly engage an upper end 19 of the container 9. The cap 17 generally has a skirt 21 adapted to be slidably inserted into the cavity 6 adjacently to the upper end 19. Alternatively, the cap 17 may be adapted to resiliently snap over a lip 23, spaced near or at the upper end 19 to form such sealing engagement, as shown in Fig. 3a. The cap 17 is adapted such that the sealing engagement hereinbefore described minimizes exposure of liquid 12 contained in the container 9 to the ambient atmosphere thereabout, which would otherwise tend to oxidize certain components of the reconstituted juice 12, thereby giving it a bland taste. The skirt 21 generally comprises one or more pour openings 25. Preferably, one of the openings 25, such as the pour opening 25, indicated by the numeral 27 in Fig. 2, permits ice (not shown) contained in the container 9 to be dispensed along with the liquid 12 contained in the container 9. Also, one of the pour openings 25, such as the pour opening 25 indicated by the numeral 29 in Fig. 2, restricts (unshown) ice contained in the container 9 from being dispensed with the liquid 12. The pour openings 25 are adapted to be selectively spaced adjacently to a spout 31 formed in the upper end 19 of the container wall 15, such as is indicated in Fig. 3. After dispensing liquid 12 from the container 9, the cap 17 can be re-adjusted such that none of the pour openings 25 are spaced adjacently to the spout 31, and the spout 31 is isolated by the skirt 21 such that exposure of the liquid 12 remaining in the container 9 to ambient atmospheric oxidation is again minimized. The spout 31 may be spaced along one side of the container 9, as shown in Fig. 2, or, alternatively, may be spaced at or near a corner 39 of the container 9. The mixing means 7 generally includes a shaft 33 connected to a mixing head 35, extending generally radially outwardly from the shaft 33. The shaft 33 is adapted to be slidably and reciprocally displaced axially through a shaft opening 37 in the cap 17. Generally, the shaft opening 37 is centrally disposed in the cap 17. A sleeve 38 surrounds the shaft opening 37 to provide reinforcement thereof. Similarly, the mixing head 35 is adapted to be slidably and reciprocally displaced axially along the cavity 11. The mixing head 35 generally has profiled cutouts 41, which are adapted to displace the liquid 12 contained in the container 9 alternately above and below the mixing head 35, substantially radially, as the shaft 33 and the mixing head 35 are reciprocally displaced relative to the container 5. If desired, the mixing head 35 may also have one or more slots 42 to assist the cutouts 41 with displacement of the liquid 12 as described herein. Generally, the mixing head 35 has fingers 43 which are adapted to cooperate with the container wall 15 and thereby prevent rotational displacement of the mixing head 35 relative to the container 9. The cutouts are also designed such that substantially equal parts of the liquid are potentially displaced clockwise and counterclockwise such that the net displacement thereof is substantially non-circular about the shaft 33 as the mixing head 35 is reciprocally displaced relative to the container 5. In addition, the axial thickness of the mixing head 35 is adapted to only moderately displace the liquid 12 axially as the mixing head 35 is reciprocally displaced relative to the container 5 to thereby minimize creation of turbulence of the liquid 12 at a free surface 44 thereof. If it is desired that the cavity 11 have a circular cross-section, the shaft opening 37 is generally non- circularly shaped, such as that indicated by numeral 45 in Fig. 3b. The cross-sectional profile of the shaft 33 is then configured, such as that indicated by numeral 47 in Fig. 3b, to cooperate with the shaft opening 45 such that the mixing head 35 cannot be displaced rotationally relative to the cap 17. It is foreseen that the mixing head 35 may be oval shaped or may have any other desired, preferably non- circular, configuration by adapting, if necessary, the cross-sectional profile 45 of the shaft 33 to cooperatively prevent relative rotational displacement between the shaft 33 and the cap 17 as herein described. The mixing means 7 generally includes a mixing handle 49 which is adapted to be grasped by either hand of a user. The mixing means 7 generally includes an upstop 51, which is adapted to limit the upward displacements of the mixing head 35 in the cavity 11 such that the mixing head 35 remains confined to submersion within the liquid 12 contained in the cavity 11 and does not break the free surface 44 of the liquid 12. If desired, a plurality of annular grooves 53 may be spaced along the shaft 33, as appropriate, to accommodate various quantities of the liquid 12 corresponding to the packaged quantities of juice concentrate commercially available. In that event, the upstop 51 is adapted to be easily removable, such as being constructed in the form of a split ring as indicated by numeral 55 in Fig. 3a, and is adapted to be easily releasably connected to the shaft 33 in a selected one of the grooves 53. A bottom end 59 of the sleeve 38 has a stop profile 61, which is adapted to receive and cooperate with the upstop 51 such that the upstop 51 is retained in the respective groove 53 in the event that the upstop 51 contacts the sleeve 38 as the juice 12 in the container 9 is being reconstituted or re- mixed. If desired, shaft indicia 62 are provided in or on the shaft 33 to correlate the respective grooves 53 with corresponding quantities of the liquid 12 contained in the cavity 11 such that initial displacements of the mixing head 35 will be confined in total emersion in the liquid 12 and thereby avoid disturbance of the free surface 44 of the liquid 12. If desired, the apparatus 1 may include a down stop 63 which is adapted to limit downward displacements of the mixing head 35 in the cavity 11. A grip 65 may be provided for handling purposes. In use, juice concentrate 67 is placed in the cavity 11 together with the water or other liquid being used to reconstitute the juice concentrate 67. The upstop 51 is snapped about one of the grooves 53 corresponding to the total quantity of liquid contained in the container 9, whereby the mixing head 35 is prevented from breaking the free surface 44 of the liquid 12 due to contact between the upstop 51 and the stop profile 61 of the bottom end 59 of the sleeve 38. The mixing head 35 is then submerged in the liquid 12 contained in the container 9 and the cap 17 is placed in sealing engagement with the container 9, generally with all of the pour openings 25 spaced non-adjacently to the spout 31. If the juice concentrate 67 is frozen or chunky, the container 9 with the juice concentrate 67 and dilutant may be allowed to stand until the juice concentrate 67 has completely thawed. Then, the mixing handle 49 is gently moved alternately upwardly and downwardly, thereby displacing the shaft 33 and the mixing head 35 axially relative to the cavity 11. As the mixing head 35 is thus displaced, the juice concentrate 67 and dilutant are alternately displaced substantially radially outwardly, moderately vertically through the respective cutouts 41, and substantially radially inwardly. Such procedure is repeated several times until the juice concentrate 67 and dilutant are thoroughly mixed. The upward and downward displacements of the mixing head 35 should be sufficiently gentle, thereby avoiding excessive turbulence of the free surface 44 of the liquid 12 such that blending of the air above the liquid 12 into the liquid 12 itself is minimized. For dispensing reconstituted liquid 12 from the apparatus 1, the cap 17 is removed from the container 9, appropriately positioned, and re-connected to the container 9 such that a selected one of the pour openings 25, either the opening 27 or the opening 29, is spaced adjacently to the spout 31. After dispensing a desired amount of the liquid 12 from the container 9, the cap 27 is again removed from the container 9, appropriately re-positioned, and again re-connected to the container 9 such that none of the pour openings 25 are spaced adjacently to the spout 31. It is foreseen that the apparatus 1 could be used for mixing and dispensing mixtures formed not only from concentrates, but also from powders, such as tea, flavored drinks, such as KoolAids>, and the like. It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.
